- DeviceTree Booting
- ------------------
- Device-tree compatible SH bootloaders are expected to provide the physical
- address of the device tree blob in r4. Since legacy bootloaders did not
- guarantee any particular initial register state, kernels built to
- inter-operate with old bootloaders must either use a builtin DTB or
- select a legacy board option (something other than CONFIG_SH_DEVICE_TREE)
- that does not use device tree. Support for the latter is being phased out
- in favor of device tree.
